The group worked several heated storylines against groups such as Los Payasos (Spanish for "The Clowns"; a group of wrestlers all dressing like clowns) as well as groups such as Los Vatos Locos ("The Crazy guys") and Los Junior Atómicos. On August 23, 1998, Mosco de la Merced, Maniaco, Psicosis II and Histeria teamed up to participate in a tournament for the vacant Mexican National Atómicos Championship, representing Los Vipers. Los Vipers won the tournament by defeating Los Payasos (Coco Amarillo, Coco Azul, Coco Negro and Coco Rojo) in the finals to win the Atómicos title.
